When we flush the toilet, it keeps making a running sound. We take off lid to tank and push the flapper down firmer and it stops. Here's the flapper:



What is the fix? Will buying new flapper help, or is there another way?

Also, if buying new flapper the route, could use help on finding right flapper. Toilet is Gerber 1.6 gpf. However, they have different models. I opened toilet and found various numbers, but none of them seems to be a model number.

Thanks.

 

Check to see that the flapper isn't binding on the pivots (should rotate up/down easily). Also, it looks like your chain may be a little too short. Usually you can adjust the length of the chain by adjusting where on the chain it attaches to the handle. There should be a little slack in the chain when the flapper is closed.

 

I would do as Bob says for sure, but if that doesn’t work, a few times I’ve had a flapper that has had just a little build up on the bottom or on the tube where the flapper sits. I cleaned the surfaces up and the leak went away. Probably not the case here but it wouldn’t hurt to try if the other things don’t work.

If you have to get a new flapper they have universal toilet flappers at Home Depot etc. . I’ve used them already with no problem – and they’re cheap enough. You could take your old flapper to the store and tell them it’s from a Gerber and I’m sure they could tell you which of the Universal’s would work.

I think sometimes the flapper gets real stiff and just won’t work anymore – but it’s all a distant memory –lol. But hopefully Bob’s suggestions will do the trick.
